Fig. lisa top plan'viewo'f a portion of the rear part of the tractor and a portion of the beam of vthe implement together with my improved `hitch. devices.

Fig. 2 is a side elevationof the hitch devices, with a portion of the, yoke-shaped member and the plow7 beam broken away.

Fig. 3 isa rear elevation ofa portion of the hitchdevices.

Fig. L is a top plan view of one of the parts of the raising and lowering device. vReferring tothe drawings, 1 represents the rear tractor Wheels, 2 the differential housing, 3 the extensions therefrom, 4 thel fenders, 5 the fender braces, and 6 the draw-bar cap of a tractor, the cap having the' usual horizontal flange 7 provided with a series of openings to which the drawv-,baris connected and which I utilize in the present case for the purpose of connecting my improvedhitchv devices. There 'is shown at 8 a pair of parallel spaced apart members which form the beam ofV the implement orare rigidly at-v tached thereto. *The ends of these members 8 are pivotally'connected by pins 9 with the arms 10 of a yoke-shaped memberV l1v which has a lateral extension 12. The central portion of this yokeshaped member has a longitudinal bore to receive a coupling pinv13,

having a bifurcatedhead 14. Clamped to the rear end of the couplingpin is atwo-part collar 15, a bolt 16, passing through a slotted opening 17 inthe pin, serving to clamp the collar to the pin, this slotted opening extending to the eXtreme rear end` of the pin.
